Type on keyboard and characters show up on LCD screen?

Projects General Guidance

Hey,

I was wondering if it was possible to hook up my keyboard so whatever I type gets displayed onto the LCD screen. Is this possible using an Arduino Uno board, or do I need the Leonardo for this? Is there anything else I would need on my computer?

I tried looking this up earlier but nothing really came up.

Any info would be greatly appreciated.

Would something like this be what you're looking for (via YouTube) - Arduino + Keyboard + LCD and the code. Looks like you would need a couple libraries, but there's links in the YouTube description.

He doesn't have an Arduino, it seems, but I would think you could do it with one? I'm sure it's possible anyways....

The guy in the video DID use an arduino.

If you want to do the same thing, get an old PS/2 keyboard and use the library. If you want to use a USB keyboard, it's going to cost you quite a bit to get a usb host shield to do the same thing.

Is there a way to possibly send the signal from a (usb) keyboard through the computer to the Arduino?

You can also use a terminal program and type into its window. Characters come out of arduino serial port. You need to print them on the lcd.
